Nope. That's a call trace, but not an oops.

Are you absolutely positive it really applies to the resource in question, as
per "drbdsetup /dev/drbd0 show"?
I'd be surprised if I saw that "BARRIER is deprecated" warning on a system that
used both an up to date RHEL kernel, and DRBD 8.3.12. Of course, something
could be messed up in the ELrepo build (incorrectly applied compatibility
wrappers at build time), or something may be fishy in DRBD itself. A not
entirely dissimilar issue was fixed in 8.4 recently, but it shouldn't affect
8.3 really so that would be a bit of a long shot.
At any rate, no way to tell without verifying that the no-disk-barrier option
is in fact enabled on your running resource.
Hope this helps,
Florian
